VACCINES COMPRISING ALUMINIUM ADJUVANTS AND HISTIDINE

摘要

To improve the stability of vaccines comprising aluminium salt(s), the invention uses the amino acid histidine. This can improve pH stability and adjuvant adsorption and can be reduce antigen hydrolysis. Histidine is preferably presen during adsorption to the aluminium salt(s). The antigen in the vaccine may be a protein or a saccharide and is preferably from N. meningitidis.
